Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and safety glasses.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Safety Warning: Ensure the vehicle is stable on jack stands before working underneath.

3. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
- Remove the wheel to access the shock/strut assembly.
- Unbolt the shock or strut from the lower control arm and the upper mounting points.
- Replace with new shock absorbers or struts, ensuring proper alignment of holes.
- Torque the bolts to manufacturer specifications (typically 40-60 ft-lbs).
Sway Bar Links:
- Inspect for damage and looseness.
- If damaged, unbolt the sway bar link from the sway bar and control arm.
- Replace with new links and torque to specified settings.
Bushings:
- Check the condition of control arm bushings and sway bar bushings.
- If worn, remove the control arm or sway bar as necessary.
- Press in new bushings and reassemble, torquing to specification.

4. Reassemble

Reinstall the wheel and lower the vehicle.
Ensure all components are secure and properly torqued.
